HENRY W. LUNCEFORD, OF LOS ANGELES, CALIFORNIA.

DOUBLE-SEAT WATER-GATE.

To all whom it may concern:

Be it known that I, HENRY W. LUNOE- roan, a citizen of the United Statesof America, residing at Los Angeles, in the county of Los Angeles, Stateof California, have invented a certain new and useful Double-SeatVVater-Gate; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to a double-seat water gate, and it may be saidto consist in the provision of the novel features and in the novel andimproved construction, arrangement and combination of the parts andmembers in the structure as will be apparent from the description andclaims which follow.

One of the objects of the invention is to provide a construction wherebythegate is adapted to be forced, by pressure of a fluid, to one or tothe other of two seats which are spaced from the gate when the latter isdisposed centrally between them.

Further objects of the invention are to provide a structure of thenature specified which is simple in character, strong and durable inuse, watertight, economical to install and maintain, effective inaction, and in which the parts may be readily assembled or demounted.

Other objects and the advantages of the invention will be apparent tothose skilled in the art from a consideration of the followingdescription of the preferred form of the structure embodying theinvention, taken in connection with the accompanying drawings in which,

Figure 1 is a side elevational view of the structure in which theinvention is applied; Fig. 2 is a central sectional view ofthe same;Fig. 3 is a view taken on the line 33 of Fig. 1; Fig. 4 is a detail ofthe gate and its connection with the screw, and Fig. 5 is a sectionalview taken on the linev 5-5 of Fig. 4.

The sections of pipe 2 may have on adjacent ends thereof the outwardlyextending flanges 3. On the periphery of the flanges 3 may be fitted theannular collars 4 formed to provide the seats 5 facing the flanges 3,the flat surfaces 6 at the top thereof, and the outwardly extendingflanges 7 joining the ends of the flat surfaces 6 and whereby thecollars may be tightly secured together Specification of Letters Patent.

by means of bolts 8 passing through the flanges 7. The gate 9 isarranged in the space between the seats 5 and it is mounted to permitmovement thereof longitudinally of the pipe sections 2 so that it willbe forced to one or the other of the seats 5 depending 011 which face ofthe gate is exerted the pressure of fluid in the pipe sections 2.

As shown, the gate 9 is slidably mounted on a rod 10 which passessubstantially centrally through the upper part of the gate 9 and has itsend portions mounted in the depending flanges 11 of two similar parts 12which may be secured together by bolts 13 passing through flanges 14thereon. The parts 12 are formed to provide in the upper end port-ionthereof a socket 15 in which may be disposed, to have a turningmovement, the enlarged portion 16 at the lower end of the screw 17. Theupper end portion of the screw 17 may. be threaded through the centralportion of the upper part of the housing 18 which latter is dis posed onthe flat surfaces 6 and is provided with flanges 19 whereby it may besecured to the flat surfaces 6 by means of bolts 19. The upper end ofthe screw 17 may l e formed with a suitable head 21 for the applicationof a wrench for turning the screw 17 to either raise or lower the gate9; also a locknut 22 may be provided on the screw 17 and it may engagewith a washer or gasket 23 on the upper end of the housing 18.

The spaces 24 between the annular collars 4 and the pipe sections 2 maybe filled with lead, cement, or other suitable material to form awater-tight joint.

l/Vhile one form of structure in which the invention may be embodied hasbeen particularly illustrated and described, many changes andmodifications thereof will readily occur to those skilled in the art,wherefore the right is reserved to all such changes and modifications asdo not depart from the spirit and scope of the invention as defined inthe appended claims.

I claim: 1. In a double seat valve gate, the combination of pipesections, collars applied to the pipe sections and provided with in-.

wardly extending annular flanges which abut against each other, theadjacent faces of the flanges being recessed to form spaced and opposedvalve seats, means for securing the collars together, a slidably mountedgate received loosely within the recessed portion so as to be seatedagainst either of the opposed valve seats, a gate operating member, anda loose connection between the gate operating member and the gatewhereby the gate is permitted to have the necessary lateral play betweenthe seats.

2. In a double seat gate, the combination of pipe sections, collarsapplied to the ends of the pipe sections and formed with inwardlyprojecting annular flanges which fit against each other, the adjacentfaces of the flanges being recessed to provide spaced and opposed seats,a slidably mounted gate loosely received within the recessed portion ofthe flanges and adapted to be moved laterally so as to engage either ofthe opposed seats, means for connecting the collars, a housing appliedto the collars, a socket within the housing, an adjusting rod swiveledto said socket for moving the same, and means adjustably connecting thegate and socket for permitting the necessary lateral play of the gatebetween the seats.

3. In a double seat gate, the combination of pipe sections, collarsapplied to the ends of the pipe sections and formed with inwardlyprojecting annular flanges which fit against each other, the adjacentfaces of the flanges being recessed to provide spaced and opposed seats,and the said recessed portion opening through the collars at one sidethereof, means for securing the collars together, a housing applied tothe collars and communicating with the recessed portion of the flanges,a slidably mounted gate loosely received within the recessed portion ofthe flanges and adapted to engage either of the opposed seats, said gatehaving an opening in the edge thereof, a socket arranged within thehousing and formed with a transverse pin which passes loosely throughthe opening of the gate to admit of the gates moving laterally so as toengage either of the seats, and an adjusting rod mounted within thehousing and having a swiveled connection with the socket.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses at Los Angelcs county of LosAngeles, State of California, this 29th day of February A. D. 1912.
